Check this list of reported bugs. There are a lot of issues with VPF that people have when they try to implement new ideas. It’s better now (some of these bugs may have been fixed) but it’s risky working with this, especially given that VPF aren’t really meant for iterated transformations every frame that would be fairly complex (moving wedges in specified paths might work, granted that these are predefined). But it is still arises that recently in this thread, surface GUIs don’t work as intended in VPF, which leaves limited options using wedges as a make-shift GUI object.
